Further to Rob's post on fuel, I wanted to raise the use of Avgas in the
H36.Avgas LL has a lead scavenging agent (Ethylene Dibromide) added.While
operating the Super Cub for many years as a glider tug we used a commercial
lead scavenging agent additive called TCP which was effective as minimising
plug fouling by lead deposits.For anyone faced with having to use Avgas this
may be an
option.https://alcorinc.com/wp-content/uploads/2012/06/TCP_FAQ_06_12_no_bleeds.pdf
Although Nigel has well summarised the technical reasons why the use of ethanol
inclusive fuels should be acceptable in the H36, anecdotally I had nothing but
problems previously with ethanol (10%) in numerous small engines including
those in water transfer pumps, pressure cleaners, mowers, brush cutters and
generators. This issue is now well know for small engines.It took me a while to
get these sorted and now I wont let ethanol anywhere near any motors including
my cars.
Best Regards
Laurie

G'day All,Make sure you download the safety data sheet for any fuel you are
considering using.
Many fuels contain heaps of volatiles like xylene toluene etc. Basically they
add paint thinners to boost the octane rating. This stuff evaporates quickly
and your octane rating plummets quickly. We had detonation once after fuel sat
around for only about 4 weeks.
We put up a sound recording on Nigel's web page here
http://www.limbachaustralia.com/downloads-useful-information/ You will need
good speakers to hear the detonation. It is like a rattling sound.
BP premium in Australia only uses benzine to boost the octane and no alcohol.
The discounted fuels tend to have the additives.
